Space Force’s new GPS satellites are months behind schedule

The Pentagon’s first batch of advanced GPS satellites, part of the GPS IIIF program, is experiencing significant delays. The initial batch is now projected to be eight to eleven months behind schedule, with the U.S. Space Force citing manufacturing issues from contractor Lockheed Martin, particularly with complex components critical to the satellites’ functionality. The first satellite, originally slated for launch in April 2026, is now expected to be delivered by November 2026.

The GPS IIIF program, a $9.2 billion initiative, aims to deploy up to 22 next-generation satellites. The first ten satellites in the series are designed to improve the GPS system with greater accuracy and enhanced jamming resistance. These upgrades will benefit both defense applications, such as targeting smart bombs, and civilian uses like navigation.

The new F-model satellites are expected to offer better navigation accuracy, compatibility with European satellites, enhanced cyberattack and jamming resistance, and improved search-and-rescue capabilities for detecting emergency beacons.

The primary challenge appears to be production delays in the Mission Data Unit, a key component for improved navigation, which is being manufactured by subcontractor L3Harris Technologies. The company is reportedly facing technical issues with this part.

Despite these setbacks, Lockheed Martin is said to be on track to meet its contracted delivery dates, though it may miss the Space Force’s preferred launch schedule. The company’s fixed-price contract includes incentives for meeting deadlines and keeping costs under budget. However, the Space Systems Command has indicated that some performance criteria have not been met, resulting in reduced profits for Lockheed Martin, though the exact financial impact has not been disclosed.

The Space Systems Command also notes that global inflation and supply chain disruptions have contributed to the delays, though it stresses that Lockheed Martin, as the primary contractor, is responsible for managing all aspects of satellite development and production.

Despite these delays, the GPS IIIF program remains a crucial part of the U.S. Space Force’s effort to modernize the GPS constellation, ensuring its ongoing reliability and effectiveness for both military and civilian needs amid growing global challenges.
